That's very useful to know. I will see how I can gather these tutorials in
a wiki. I think I will discuss with the rest of team how to organize them.

Just a little extra tip you could include in your wiki page. Will

reworking of course.
I was actually an Offset Printer for more than 20 years, computers and
photography were only hobbies. Probably where my mental issues come from -
heavy metal poisoning.
There's a big mistake that nearly all graphic designers make, especially
if they're fresh out of TAFE with a shiny new certificate in Photoshop.
Paper is only paper, if you put too much ink on it it gets soggy and
changes shape. This is really noticeable in colours such as the dark blue
for Fedora and in any darker areas of the image.
The problem is that when you do a default separation your software by
default will use all four colours to make black, even though one of those
colours is black.
This was way before I started playing with the Gimp, maybe Gimp gets it
right, I don't know. The old Quark used to do the separations correctly but
Photoshop is hopeless, what you have to do is lift all the black out of
your image as a separate layer first, and put it to one side as the
finished black layer. Then do your cmyk separation, the black layer should
be blank and the colour layers should be almost empty any where the black
was.
I was a "short run speciality" printer, someone else did the 50000
posters, I did the 300 corporate invites. If you are truly after a high
quality result use cmyk for the photos only and use "spot colours" for the
rest of the design. It's not uncommon in my trade to get a job that's
listed as "7 colours, 2 sides, + 2 varnishes and a spot varnish"
The spot varnish is a clever little trick, you give the finished print an
over all gloss varnish first, then use one of the same printing plates from
the job, usually the Cyan, and print a matt varnish over the top. This
trick can be used to attract peoples attention to an area of the design
without making it too obvious that this is what you want.
Cheers,
Andrew.
